Laravel 5.6 可信代理错误

php laravel proxy laravel-5.6

我今天已经从L5.5升级到L5.6（在此过程中将Symfony组件更新到v4）。此外，我已经将软件包更新到4.0作为官方Laravel 5.6升级指南。fideloper/proxy

之后，我开始收到此错误：Type error: Argument 2 passed to Symfony\Component\HttpFoundation\Request::setTrustedProxies() must be of the type integer, array given, called in /var/www/html/vendor/fideloper/proxy/src/TrustProxies.php on line 54

Symfony 4 确实期望整数（位掩码）作为第二个参数：Symfony\Component\HttpFoundation\Request::setTrustedProxies()

/**
* Sets a list of trusted proxies.
*
* You should only list the reverse proxies that you manage directly.
*
* @param array $proxies          A list of trusted proxies
* @param int   $trustedHeaderSet A bit field of Request::HEADER_*, to set which headers to trust from your proxies
*
* @throws \InvalidArgumentException When $trustedHeaderSet is invalid
*/
public static function setTrustedProxies(array $proxies, int $trustedHeaderSet)
{
    self::$trustedProxies = $proxies;
    self::$trustedHeaderSet = $trustedHeaderSet;
}

4.0 确实给出了一个数组而不是一个整数进入这个函数：fideloper/proxy

public function handle(Request $request, Closure $next)
{
    $request::setTrustedProxies([], $this->getTrustedHeaderNames()); // Reset trusted proxies between requests
    $this->setTrustedProxyIpAddresses($request);
    return $next($request);
}

和

/**
 * Retrieve trusted header name(s), falling back to defaults if config not set.
 *
 * @return array
 */
protected function getTrustedHeaderNames()
{
    return $this->headers ?: $this->config->get('trustedproxy.headers');
}

所以我无法理解这是错误还是我只是错过了什么？fideloper/proxy

答案 1

经过一些调查（Winmerge与Laravel 5.6的全新安装进行比较），这归结为文件的差异：app\Http\Middleware\TrustProxies.php

拉拉维尔 5.5：

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Fideloper\Proxy\TrustProxies as Middleware;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array
     */
    protected $proxies;

    /**
     * The current proxy header mappings.
     *
     * @var array
     */
    protected $headers = [
        Request::HEADER_FORWARDED => 'FORWARDED',
        Request::HEADER_X_FORWARDED_FOR => 'X_FORWARDED_FOR',
        Request::HEADER_X_FORWARDED_HOST => 'X_FORWARDED_HOST',
        Request::HEADER_X_FORWARDED_PORT => 'X_FORWARDED_PORT',
        Request::HEADER_X_FORWARDED_PROTO => 'X_FORWARDED_PROTO',
    ];
}

拉拉维尔 5.6：

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Fideloper\Proxy\TrustProxies as Middleware;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array
     */
    protected $proxies;

    /**
     * The headers that should be used to detect proxies.
     *
     * @var string
     */
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
}

因此，设置受保护的$headers = Request：：HEADER_X_FORWARDED_ALL;根据 Laravel 5.6 版本

答案 2

打开。app\Http\Middleware\TrustProxies.php

更改以下内容

protected $headers = [
    Request::HEADER_FORWARDED => 'FORWARDED',
    Request::HEADER_X_FORWARDED_FOR => 'X_FORWARDED_FOR',
    Request::HEADER_X_FORWARDED_HOST => 'X_FORWARDED_HOST',
    Request::HEADER_X_FORWARDED_PORT => 'X_FORWARDED_PORT',
    Request::HEADER_X_FORWARDED_PROTO => 'X_FORWARDED_PROTO',
];

自

protected $headers = Request::HEADER_X_FORWARDED_ALL;
